Testing Spring MVC API: No qualifying bean found

Question

I have the following structure of by Spring MVC API with a single end-point getAnnotation :

@SpringBootApplication
public class Application {
    @Bean
    public javax.validation.Validator localValidatorFactoryBean() {
        return new LocalValidatorFactoryBean();
    }

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}


@Service
public class MyAnalyzerImpl implements MyAnalyzer
{

    @Autowired
    public MyAnalyzerImpl() {}

    @Override
    public Annotations getAnnotation(MyRequest request)
    {
        // ...
    }
}

Interface

public interface MyAnalyzer {
    Annotations getAnnotation(MyRequest request);
}

Controller

@RestController
@RequestMapping("/thisapi/{id}")
public class MyController {

    @Autowired
    @Qualifier("MyAnalysis")
    MyAnalyzer myAnalyzer;

    @RequestMapping(value = "/getAnnotation", method = RequestMethod.GET)
    public Annotations getAnnotation(@PathVariable String docId,
                                     @RequestParam(value = "document", defaultValue = "{'id':'1','title':'bla-bla'}") String text) {
        MysRequest myRequest = new MyRequest(MyRequest.TYPE_ANNOTATION, text);
        return myAnalyzer.getAnnotation(myRequest);
    }
}

To test the API, I firstly created src/test/java/MyAnalyzerImplTest.java and was able to successfully execute it:

@RunWith(SpringJUnit4ClassRunner.class)
public class MyAnalyzerImplTest {

    private MyAnalyzerImpl myAnalyzer;
    private String sampleText;

    @Test
    public void testEndpoint() throws Exception {
        MyRequest request = new MyRequest(  MyRequest.TYPE_ANNOTATION,
                                                    "1",
                                                    sampleText
                                                 );
        Annotations results = myAnalyzer.getAnnotation(request);
        Assert.assertTrue("This " + results.getPayload().getWords().size() + ") " +
                "should be greater than 0", results.getPayload().getWords().size() > 0);
    }

    @Before
    public void setUp() throws Exception {
        myAnalyzer = new MyAnalyzerImpl();
        File f = new File("src/test/resources/texsts/text.json");
        if (f.exists()){
            InputStream is = new FileInputStream("src/test/resources/texts/text.json");
            samplePublication = IOUtils.toString(is);
        }
        Thread.sleep(1000);
    }

}

Now I want to run Application.java to launch API at the address http://localhost:8080 . I get the following error:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'myController': Unsatisfied dependency expressed through field 'myAnalyzer': No qualifying bean of type [org.api.thistool.MyAnalyzer] found for dependency [org.api.thistool.MyAnalyzer]: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true), @org.springframework.beans.factory.annotation.Qualifier(value=MyAnalysis)}; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.api.thistool.MyAnalyzer] found for dependency [org.api.thistool.MyAnalyzer]: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true), @org.springframework.beans.factory.annotation.Qualifier(value=MyAnalysis)}

Just in case I also provide the RAML file.

Answer 1

As discussed in the comments, original error was due to the use of invalid qualifier @Qualifier("MyAnalysis") . No bean for id "MyAnalysis" is present in the context. Since there's only one suitable implementation using additional @Qualifier is useless.

Second error was because of the invalid use of @Autowired with constructor. Similiar issue is described here
